Unpacking the nuances: an exploratory multilevel analysis on the operationalization of integrated STEM education and student attitudinal change

Integrated STEM education (iSTEM) is recognized for its potential to improve students’ scientific and mathematical knowledge, as well as to nurture positive attitudes toward STEM, which are essential for motivating students to consider STEM-related careers. While prior studies have examined the relationship between specific iSTEM activities or curricula and changes in student attitudes, research is lacking on how the aspects of iSTEM are operationalized and their influence on shifts in student attitudes towards STEM, especially when considering the role of demographic factors. Addressing this gap, our study applied multilevel modeling to analyze how different iSTEM aspects and demographic variables predict changes in student attitudes. Drawing on data from two five-year NSF-funded projects, we evaluated pre- and post-attitude survey responses from 948 students. Our analysis identified two key iSTEM aspects—relating content to students’ lives and engagement in engineering design—that significantly influence positive attitude change. The results highlight the importance of curriculum relevance and hands-on, problem-solving activities in shaping student attitudes. However, the impact of these instructional strategies varies across demographic groups. The study’s insights into the differential impact of iSTEM aspects on diverse student groups provide actionable guidance for educators, curriculum developers, and policymakers aiming to enhance STEM learning experiences and outcomes.
